Scary study links movie popcorn and Alzheimer's

You already knew movie-theater popcorn was bad for you -- but you probably didn't think it was this bad. A new study conducted by the Center for Drug Design at the University of Minnesota has uncovered a scary link between diacetyl, an additive that gives popcorn its buttery taste and smell, and Alzheimer's disease. Diacetyl apparently leads to the clumping of beta-amyloid proteins in the brain -- an indicator of the disease. Besides movie-theater popcorn, diacetyl is also used in some margarines and candies, as well as beer. [Source]
